Hi,

I am going to use Javassist to do some education project.
But I have so many problems and questions if I should use Javassist or other library.


1. retrieve all the variable names and its corresponding values (global variables, and local variables) ?

2. can I insert a statement into a specific line within a method?
for example,

public void init() {
int a = 10;
// <<<<<<< insert a statement here : a = a * a;
System.out.println(a);
}

3. can I modify a specific statement ?
for example,

public void init(int x) {
return x; //<<<<<<< modify it to: return (x * 2);
}


Would you please to show me some example about the above questions ???
Please give me a hand !!! It's very urgent for me...
Thanks a lot.


Best regadrs,
Eric
